Well, I have 7complete not infinite, but these features are included in complete too.
The new spectral 2 clouds were promising and are wonderful. A bit slow but well worth it.
Painting in all 4 windows is a pleasure but I couldnt use it properly because of the bug that 'undo' makes the eco disappear. I dont mind re-populating but re-painting is too much. This  bug is now supposedly fixed but I have no time to implement and test at the moment - real painting(watercolor) week now.
The new water is disappointing so far - I was looking forwards to choppy/stormy seas but when the camera is close to the water I get weird sharp lines. Quite likely that I havnt learned how to use  it well yet.

I'm looking forward to the new features in 7.4 like painting material distributions on terrains.Sky preview with clouds would be nice too but that's only promised for inf :(

"I paint that which comes from the imagination or from dreams, or from an unconscious drive. I photograph the things that I do not wish to paint, the things which already have an existence."
